STOP FOR ELEVATED CARRIERS.

Application filed March 30, 1908. Serial No. 424,082.

Likewise it may be placed again on the wire by reversing the operation, and when the other end is attached to the stop block S it is ready for operation. The open coil R will usually rest against the closed coil which forms the loop L and the stop block S will pormally be held at some distance from this oop.

The carrier being run with force along the track A, the hood H will come in contact with the block and will slide it along the track where it assumes the position shown in Fig. 2, or a position even closer to the open coil It, resting against the loop L. The movement of the carrier being-arrested by the resistance of the spring the rebound of the spring will start the carrier back on the track. By this means the carrier is revented from running against the loop i or the hook of the tension bolt B where it would be liable to get damaged or run ofi the track and then it is started back on its return trip which is also an advantage.

The stop block may be made in any sha e so its meeting end will 'th tiie To all whom it may concern:

Be it known that I, ALBERT H. NELLER, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Imrovement in Stops for Elevated Carriers, of which the following is a specification.

My invention relates to a stop to arrest the movement of a carrier on an elevated track and it consists of the features set forth in this s ecification and definitely pointed out in the c aims.

In the accompanying drawings forming a part of this s ecification, Figure 1 is a side view ofan e evated track embodying my invention, and showing a portion of a carrier mounted thereon. Fig. 2 is the same showing the working parts in a different position. Fig. 3 is a transverse section on line 33 of Fig. 2-. Fig. 4 is an enlarged detail which will be hereinafter described.

Referring to the drawings, A represents the track which is shown as a wire stretched taut between supports, one of which is shown as a post P. A threaded tension bolt B, having a hook, is passed through the head of the post and a loop L is formed on the end of the correspond W1 portion of the carrier which comes in contact with it. In the drawings it is shown rectangular so as to roperly meet and push against the hood without injuring it or causing the wheel to leave the track, but such modifications may be made as will enable it to contact with other styles of carriers. Should it be desired to arrest the carrier at some distance from the end of the track, a stationary stop may be secured to the wire, (as will readily occur to those skilled in the art), against which the open coil B may rest in place of the loop L.

Any form of spring may be used which will secure the necessary amount of resiliency for the stop block S. The form shown is preferable because its weight below the track will hold the block in proper position and it can be readily adjusted on the track and be easily removed therefrom. The coil E in the center, being at the lowest point, adds to the proper balance of the device as well as its resiliency.

The drawings O represents a portion of a carrier frame having a hood H containing a wheel W to run on the wire.

S is a stop block which is secured to the wire by means of a recessed plate T which is secured to the underside of the block by means of screws or nails N. The recess in the late should be large enough to permit the lock to slide readily back and forth on the wire.

D is a spring wire having a coil E near its center. One of its ends is bent at substantially right angles to the adjoining part of its body, and this end is passed through a hole in the block S and is held in place by a key K, a washer 0 preferably being placed behind I the key. The other end of the spring is fitted with an open coil R which is adapted to catch over and slide upon the wire, and to be readily placed thereon or removed therefrom. This end with its open coil is most plainly shown in enlarged Fi 4. When the other end is free from the block S, it may be readily removed from the wire by twisting the spring around so the point I will pass behind the wire when the coil may be lifted off the wire.

show the stop applied to a wire track but by changing the attaching parts to suit it may be applied to any style of track, and other changes may be made in the details without departing from the spirit of my invention.

What I claim is 1. The combination of an elevated track, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and resilient means having one end applied directly to the track and the other connected to the stop to ease the arrest of the carrier and to cause a rebound of the same.-

2. The combination of an elevated track,- a carrier to run on the track,- a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and a spring having one end directly applied to the track and the other connected to the stop to ease the arrest of the carrier and to cause a rebound of the same. i

3. The combination of an elevated track, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and a depending spring having one end directly applied to the track and the other connected to the stop to ease the arrest of the carrier and to cause a rebound of the same.

4. The combination of an elevated track, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and a depending spring having a coil near its lower central portion with one end directly applied to the track and the other connected to the stop to ease the arrest of the carrier and to cause a rebound of the same.

5. The combination of an elevated track, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and a depending V-shaped spring having one end connected to the stop and the other end having an open coil adapted to encircle the track and to rest against a fixed stop.

6. The combination of an elevated track, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track andslidable thereon, and a depending V-shaped spring with a coiled spring near its central portion and having one end connected to the stop and the other end having an open coil adapted to encircle the track and to rest against a fixed stop..

7. The combination of an elevated track Wire having a loop at one end, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and a depending V shaped spring having one end connected to the stop and the other end having an open coil adaptpd to encircle the Wire and rest against the oop.

8. The combination of an elevated track Wire having a loop at one end, a carrier to run on the track, a stop to arrest the movement of the carrier mounted on the track and slidable thereon, and a depending V shaped spring having one end bent at right angles and passed through a hole in the stop and its other end applied to the track Wire, substantially as described.

9. In a device of the character described, an elevated track, a carrier to run on the track, a stop-block adapted to rest on the track, a recessed plate applied to the block so as to embrace the track and permit the block to slide thereon and a spring connected to the block as and for the purpose set forth.
